Ofcom are useless.
I'd been with EE for years (out of contract, SIM-only) but at that time they didn't do unlimited data plans and so I made a very temporary move to Three (terrible coverage back then).
When I went back to EE, I signed a 24 month contract. It was for two numbers - my own and one for my son.
For his, I took only 25GB of data, because on the call I was assured I could gift 100GB a month of my own allowance.
Except:
1. You can't. You can only ever gift a maximum of 99.5GB - it won't let you gift the last 500MB - that's potentially a lot of data they are stealing from customers.
2. Because they have such antiquated systems, they have to add a "100GB pot" onto your unlimited data - and it's from this "pot" that you can gift.
3. Except - any data you use is first taken from that pot, so unless you remember to gift it at the start of each month, you lose out what you can gift
Nowhere on EE's site or in my contract were these terms noted.
Nowhere was it explained during the time I took out the contract.
No one I spoke to at EE in their support teams knew this was the case except for one person in their (I think) third line who I was put through to because "Oh I know someone who can explain this"
So I complained.
Ofcom were utterly useless.
The kept saying "It clearly states you can gift up to 100GB of data" - without listening to the root cause of my complaint.
They then - and this is the kicker - referred to the contract uploaded by EE. Not a copy of my signed contract. Oh no. An updated one that was more descriptive and dated some months after the version I signed. And refused to listen when I explained it. They just kept saying "but it's in the contract".
Fucking pointless entity.
